regorafenib phase i study in mainland chinese patients

Conditions: Oncology

Summary: the primary objective of this study is to define the pharmacokinetic of regorafenib administered orally as a single agent in chinese patients with advance solid tumors. the second objective include the evaluation of safety, tolerability, and efficacy of chinese patents treated with regorafenib
